My current project is Phergie, an IRC bot written in PHP 5 with an object-oriented API. Feel free to visit with me about the project in #phergie on the Freenode IRC network.
I've made a few contributions to the Zend Framework project. One is the Zend_Service_Simpy module, which wraps the REST API for the Simpy social bookmarking service. The other is the proposal and some code for the Zend_Service_RememberTheMilk module, which wraps the REST API for the Remember The Milk to-do list service.
I also contributed some of the work done on version 1.6 of the Simple AJAX Code-Kit.
I've written a Send to paste2.org PHP script, which takes data sent to stdin and posts it to the site paste2.org using the cURL extension. Comments at the top of the file include instructions on use from vim, but it should also be usable in any other text editors that support piping line ranges to stdout.
